Defending the country during the Spring and Autumn Period was a joke.

In 722 BC, Wei launched a war and attacked Zheng, but Wei did not get good results from the powerful Zheng in the war. Even in 7 19 BC, when he joined forces with other three countries to attack Zheng, he was still losing ground, which not only humiliated the country, but also seriously weakened its strength.

In 7 15 BC, Qi reconciled the relationship between Wei and Zheng for its hegemony. In 7 13 AD, Zheng crusaded against Lu, and Wei Zhen sent troops to help, which actually annoyed Lu. Lu joined forces with Qi, Song and Cai to attack Wei. In 666 BC, Wei also foolishly fought against the overbearing Qi State.

But at this time, the monarch did not reflect on himself, but became more extravagant and dissolute. Finally, when Rongdi invaded, the whole country fell apart, Wei Yigong was killed and the country was conquered.

In the later period, Guo Wei accepted the help of Qi and Song, and revived the country for a short time. However, Guo Wei, who experienced great storms, was not as good as before, unable to compete with other vassal States, and even became the object of division among neighboring vassal States. According to Records of the Historian, in the Wei Dynasty. Strong Sanjin, who is like Hou Yaozong, belongs to it? This shows that Weiguo at that time has become a vacillating vassal state.

When Wei arrived, Qin had already defeated the six countries, so? In the 14th year of Yuan Jun, Qin conquered Wei Dong, Qin Chu established Dong County, moved to Wang County, and Puyang was Dong County. ? At that time, only Wang Ye County defended the country. In 209 BC, Qin Ershi abolished the horn of the last monarch of Wei State, which ruled for the longest time in the Zhou Dynasty, and Wei State really perished.

Although its existence did not have much influence on Qin's unification of the whole country, when it was forced to move to the wild king in the later period, it was no longer conspicuous, but more like an autonomous state and county, in name only. However, it undoubtedly left a good reputation. Formally speaking, after all, it did die after the Six Great Powers, not at the hands of Qin Shihuang, and enjoyed the country for more than 900 years, more than 800 years in the Zhou Dynasty.
